I have deployed kamailio-ims-5.3.5 as docker containers. I had private IP for containers.

So when i try to establish a call from the public network , The via header is taken as container Private IP even if i use advertise address as public IP. 

So ACK is not reaching the pcscf from ue. Any idea can be provided for this issue.

Kindly help.

Thanks,
